I

In the preliminary movement of the vehi cleto the desired locality for operation, and l which is effected by the power of the motor. -1 I on the vehicle, the portion 43 of the frictionclutch is moved by the lever 45. into engagement with the portion on the driving- 7 shaft 39 .of the en ine, and'the power is transmitted through's aft 41 and the pinion 54,- r15 which is in engagement with gear 64, to the tumblershaft 66 and. thence throu h the beveled pinion and the gear 71 to t e rear axle of thevehicle, the dlrectionof movement of, thevehicle being controlled by the 1 2o I lever 34.

In the operation of 'the ap aratus for re movin the dust from the wal or other surfaces t e lever 59 on the vehicle is operated to move the portion 55 of the clutch on shaft -1 2 41 into engagement with the portion 74' on the fan-shaft of the air suction and forcing apparatus 72, which simultaneously moves t e pinion 54from engagement with the ear 64, and the suction being communicate to coupling of the ordi ary description, with whichis connected one end ofthe fiexible dust-conductingpipe or hose 116, which qis v of suitable length, U onthe outer end of "said ipe areconnected ranch ipes or 'noz- -"the tank 76 a vacuum is formedin the tank,

passing into the pi e 116 and thence to the tank76, in which t e fan-blades 99 are set in operation by the force of the incoming currents of'air, the ra idity of rotation of the blades bein" controlled thereby, and the action of the an-blades se' arates the body of the dust and forms eddies, into which the dust falls upon the inclined surfaces of the plates 100 and thence falls upon the bottom 103 of the tank, the air bein drawn out of the tank throu h the cone-s aped pipe 93, passing the fanlades 99, as indlcated y the arrows in Fig. 4. When the tank 76 becomes laden with dust, the catch 107 is released, and the bottom falls downwardly, discharging the dust, after which the bottom, which is hermetically sealed by the asket 106, is closed and secured as before. S ould the action of the suction and force apparatus create a vacuum in the tank greater than is necessary, the relief-valve 85 in the exhaustpipe 80, which is held by the spring 92 to a degree of resistance necessary to effect the best results, opens automatically and the action of the fan is not impeded. The dust in entering the tank 76 may be interceptedat the top of the tank, as seen in 8, in which the deflectingplates 100* extend from a point below the receiving-opening for the dust downwardly in inclined lanes part way to the bottom of the tank. In this arrangement the fan-blades 99* are obviously reduced in length and rotate within the reduced space concentric with the inner edges of the ribs or plates below and adjacent to the end of the cone. These deflecting-plates may be spiral and also per endicular, as the conditions may require. Vhen it is desired to disinfect the premises from which the dust has been removed, the cup 86 above the reliefvalve in the exhaust -pipe 80 is filled with the disinfectant powder or liquid and discharged through the pipe 75, connected with the blast-openin on the fan-case 72, and through the flexibi pipe 7 0 directed to deflecting devices within the place, and thedisinfectant is distributed insaid tank, an air-suction apparatus connectedwith the tank, and a rot'ary'se arating-fan within the tank, energized by t e air entering and passing through the tank.

In a pneumatic, dust-collecting apparatus, the combination with a vacuum-tank for the dust, and with a conductor for-the dust leading to the tank, of dust-deflecting plates within said tank, an air-suction ap aratus connected with the tank, a rotary ihn within the tank actuated by the air entering and passing through the tank, and means between the suction a paratus and the entrance to the tank sel -acting to regulate the exhaust from the tank.
